A RK-20 need exactly 104192 welding wire , i broke 3 down and all times i got out i used exactly this amount.

skill/ped = 3.45/36 = ~0.0958

The Rk-5 in Non-SIB is, depending on the price you pay for equipment, up to 60% more efficient then a RK-20 during SIB !!

With another chipping-tool, i calculated the skills you need to unlock the “Blueprint Comprehension” skill on level 10 in the “Vehicle Structural Engineer” profession.
It is estimated by 17 ped TTvalue in skills (ESI-estimation).
This equals, depending on your intelligence roughly on 8 x RK-5 tools full TT which you need to burn on repairing.

I don’t know how many skills in Engineering are neccessary to finish “mentoring” , so i cant give you any calculations about this. But most people i asked said around 25 x RK-5 Full TT are needed.

For level 100 was pretty difficult to get data which are close to reality.

The chipping optimizer tool went a bit mad.

So i could figure out , that with the right % spread on the different skills is a estimated ESI in Skills by

21000 Ped.

This skills are spread out on ALL depending skill “scientist included”.

If you would use only RK-5 tools it would take you roughly 7250 RK-5 tools to gain level 100.

7250 * 3.2 hours (per tool in perma use) => 23200 hours.

If you would space repair 12 hours per day you could do it in 1933 days or around 5.3 years………….
